Why do electrons enter the 4s orbital before entering the 3d orbital?

because the 3d orbital is at a lower energy level

because both the 4s and 3d orbitals are at the same energy level

because the 4s orbital is at a lower energy level

because the 4s orbital is at a higher energy level

i think its c. let me know if you make a 100 on plato.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
